PROBLEM TO BE SOLVED: To eliminate movements of body materials and chuck members obliquely or in a zigzag manner without impairing its external appearance without deforming a heat sealed part of the body material in a bag making machine for manufacturing a plastic bag with a chuck tape. SOLUTION: A driving mechanism 10 is coupled to a receiving plate 5. A controller 11 is connected to the mechanism 10. After body materials 2L, 2H and a chuck material are heat sealed, the mechanism 10 is driven by the controller. And, the plate 5 is once raised, and a heat sealing bar IL of a lower side is remotely moved. Thereafter, before next heat sealing, the mechanism 10 is driven by the controller, the plate 5 is lowered to an original position to approach to the bar 1L of the lower side. |
